New Virus in Greenhouse Crops: Important Info Sessions Available Tues and Thurs

ToBRFV is a new virus on the greenhouse scene.

A new, potentially serious plant virus – the Tomato Brown Rugose Fruit Virus – is moving through crops across Europe and the U.S.  As this virus can affect both tomatoes, peppers, and potentially some floral hosts, OMAFRA is running information workshops in Niagara and Leamington to answer grower questions about potential threats to our industry.

Read on for a description of the virus and workshop dates.

LOOK OUT! Here comes the Spider Man! (Oops. I mean Mites. Spider mites. Sorry; way less exciting).

spider mite-GillianFWeekly-mum producers have seen higher-than-normal spider mite levels coming in on cuttings from the U.S. recently.  This might impact seasonal potted-mum growers as well.

Here’s some tips and tricks on two spotted spider mite control within a chrysanthemum IPM program.

It’s “B” Season! Watch for Botrytis, Broad Mite and Burn.

Honeybee 2Although native bees and honeybees may just be starting to gather strength and are beginning to fly outside, other “B’s” have been of growing concern in the greenhouse for some time now.

These include common spring bedding crop problems like Botrytis cinera (aka grey mold), Broad mites, and leaf burn (from a variety of causes).

Keep reading for tips on how to manage these issues during this time of year.

Using Beleaf (flonicamid) as a drench: benefits and (potential) drawbacks.

gi_0_beleafGiven that it’s the season for pest problems like aphids on spring crops, I’d like to remind everyone of an important new pest management tool we have at our disposal.

Thanks to the hard work of Cary Gates at Flowers Canada Growers, and OMAFRA’s Jim Chaput, Beleaf (flonicamid) can now be used as a drench on greenhouse-grown ornamentals and cut flowers.

Read on for more details regarding the expanded label and potential phytoxicity issues.

Spring crops that are “magnets”for certain pests.

aphid_cali_UMAssYou know the old rhyme: “April showers bring May flowers, but what do May flowers bring? Aphids“. Or sometimes it seems that way, anyways, with Spring bedding crops.

To help guide your pest management program this year, our  friends (superiors?) over at Michigan State Extension have released a handy  list of which crops are likely to attract which pests.  Keep reading for more info.

Supplemental Lighting Options for Bedding Plant Seedling Production

Happy spring!  With the season in full swing, we know that growers are busy this month.  I read an interesting article on the effects of supplemental LED lighting in bedding plants this week, and I’ve summarized it here with the key messages at the bottom of this post.  It seems like an appropriate article for the season, especially if you are starting to think ahead to how you might improve production for the 2017 spring season.

Much of the LED lighting research done in ornamental plants has focused on finding the best wavelengths for plant production.  This can vary based on the plant being grown, and the qualities desired.  Before we dive into the study, let’s review some of the reasons why you might consider LED lights from a plant production standpoint.
